hpplicationifiled June 9 1917.

To all whom it may concern.

Be it known that I, HENRY W. HARTEL, a

. citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Cut-Out for Internal-Combustion Engines, of which the following is a specification.

My invention relates to the general class of muffler and other cut-outs, one of the principal applications of which is to automobiles.

enerally stated, I provide means arranged in or applied to the exhaust pipe of an engine of the gas or hydrocarbon internal-combustion type, by the use of which the exhaust gases may be directed to the atmosphere, without passing through the muffler of an automobile. Incident to my invention and among its objects are complete closure of the ports, direct expulsion of the exhaust gases and adaptation of the parts for the setting of the valve to take up wear.

With the foregoing and other objects in view, my invention comprehends the devlces represented in the accompanying drawings, explained in the specification, and hereinafter particularly specified in the clalrns.

For the purpose of illustrating my invention in its most comprehensive scope, I have shown in the accompanying drawings certain typical embodiments of it which are at present preferred by me because in practice they have given satisfactory and reliableresults.

Referring to the drawings.

Figure 1 represents in side elevation a cutout embodying my invention in one of its preferred forms.

Fig. 2 represents a longitudinal, sectional, elevation of the cut-out represented in-Fig. 1, section being taken on theline 22 of Fig. 3.

Fig. 3 represents a transverse sectional elevation on line 33 of Fig. 1; and Fig. 4 a fragmentary, perspective view of the valve proper removed from its chamber.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings, l2 designate the outer ends of a valve casing, preferably bell-shaped, correspondingly-opposite and outwardly-extending, and which embody between them a cylindrically formed valve chamber 3, integral with them and into which they respectively open through con- Specification of Letters Patent.

tracted throats constituting an and an outlet port 5.

6 represents a gas inlet gine, through which when the valve is open, the exhaust gases are carried through the valve chamber 3 to the gas outlet pipe 7 to inlet port at pipe from the en- Right angularly with respect to the inlet and outlet ports 4 and 5 of the body of the is an exhaust port 8, which in the embodiment-under consideration is shown as opening downwardly from out the valve chamber 3, and as being supplied with an exhaust deflector 9, which deflects the gas outwardly and rearwardly.

The valve proper is a cut-away cylinder, so to speak,that is to say, if it were of continuous solid form, it would be a true cylinder, but which, as I construct it in the embodiment under-consideration is composed essentially of end members 11 and 12, between and connecting which is the body 10. This body 10 is the wall of the valve, and is adapted to the extent of its circumferential segmental area to fit within the internal, hollow, cylindric valve chamber 3, and according toits position rotatively considered, is adapter to close either the gas inlet port, the gas outlet port or the gas exhaust port.

In the construction under discussion, the valve heads 11 and 12, being adapted to effect a close fit within the ends of the cylindric valve chamber, themselves form and effect an axial support for the valve considered as an entiretyand enable me to dispense with other supports.

The control of the valve may be effected by various means of which a lever and link connection spi'ingcontrolled to effect auto- 9 matic return of the valve, is that which I prefer. Assume'the valve in place as shown in Figs. 1, 2, and 3, and referring particularly to Fig. 3, it will be noticed that the outer part of the valve head 11, which is simply a lateral extehsion of it but designated 13, is fitted within the outer edge opening of the valve chamber, which for clearness I have designated 1%, so as to make a tight closure, and that this extension which as explained is lateral, is further radially extended to form a lever 15 to which a link 16 is connected through the pivot 17.

Obviously the throw of the lever through Patented July 5, 1921.

'sible'to perform the necessary of the valve to such an extent as will cause the wall 10 of the valve to open or close the desired port,,as for instance, to throw the wall from the position shown in Fig. 2, in

full lines, to that shown in dotted hnes in said figure.

The valve head 12 is inclosed tightly within the outer end of the valve chamber and formed to fit therein, as shown in Fig. 3,

and the retention of the valve within the chamber is conveniently effected by a'retaine ing screw 18.

If, as is obvious, there were no control of the valve except that resulting from the connection of the lever and link, the retention of the valve in a given position of portclosure would be dependent upon them alone.'

In order, therefore, to effect the automatic return of the valve from a given position into which it may be turned by the link and lever, I provide a spring-return-control which in the form under discussion, is a spring bar 19 connected at its inner end with a retaining stud 20 on the valve casing, and at its other or free end introduced withina socket 21 on the'inner face of the lever 15 The play of this control rod referably both to its socket in .the lever and its internal hollow seat in the stud, is such as to give it the required freedom of movement-t0 accomplish the desired end.

' In this preferred organization, it will be understood that the form of the wall 10 of the valve proper, which is internally segmental and more or less in reverse of its external segmental contour, is of the essence of. this construction because it makes it posfunctions of being externally adapted to close the ports and of' being also the connective medium which unites and retains in their proper places, the valve heads 11 and 12..

Such being a description of my invention, it is to be understood that in using the expression rotary as appliedto the valves, I

donot use it in'the sense of a complete rot'ation,rbut 1n the sense of oscillatory, because at no time does the valve itself make a complete rotation, but only such rotation as V makesit possiblefor it to'close' one ofthe three ports, happeni'ngto be 'the selected port, and open the other two.. It :will now be apparent that I have devised a novel and useful automobile cut-out valve, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above. description and while I have, in thepresent instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is-to be understood that such embodiment is susceptible of modification invarious particulars spirit or scope of the invention or. sacrificing any of its .advantages.

Having thus descrlbed my "invention what I claim as new anddesire to .secure by Letters Patent, is e 1. A cut-out for internal .combust-ioniengines, comprising a casing havingan inlet 'and an outlet, an exhaust port, an exhaust deflector in proximity tosaid port and a cylindrical bore, one end. of which is closed and the other open, a valve having a head at each endand its body portion forming 'a segment of a cylinder, a fastening device passing through the closed end of thebore and connected with the juxtaposed" valve head, and means to actuate said valve.

2; A cut-out for internal combustion engines, comprising a casing having an inlet one end of which 1s open and an outlet port, an exhaust port and'a cylindrical bore, and the other end of which is closed, a rotatable valve in said bore having'an inner and an outer valve head and the portion therebetween forming the segment of a cylinder,

means passing through the closed'end of said bore and connected with the juxtaposed valve head to retain thevalve in position,

said outer valve head having an arm projecting'there-from, and a spring bar one end of which is connected to said arm and the other endof which engages a fixed portion of the casing. r

In testimony whereof I have hereunto signed my name this 26th dav of'May', 1917.
